20a216fe6f 0026075: Make Extrema_GenExtCC return IsParallel flag in case of parallel curves
1) Added check for parallel curves.
2) Changed unefficient o(n^2) duplicates deleting algorithm to o(n) algorithm.
3) Deleted useless upper level duplicates deleting algorithm.

94f71cad33 0024682: Move out B-spline cache from curves and surfaces to dedicated classes BSplCLib_Cache and BSplSLib_Cache
1. B-spline cache was moved into separated classes: BSplCLib_Cache for 2D and 3D curves and BSplSLib_Cache for surfaces.

2. The cache is used now in corresponding adaptor classes (Geom2dAdaptor_Curve, GeomAdaptor_Curve and GeomAdaptor_Surface) when the curve or surface is a B-spline.

3. Algorithms were changed to use adaptors for B-spline calculations instead of curves or surfaces.

4. Precised calculation of derivatives of surface of revolution is implemented for the points of surface placed on the axis of revolution (Geom_SurfaceOfRevolution.cxx)

5. Small modifications are made to adjust algorithms to new behavior of B-spline calculation.

6. Test cases were modified according to the modern behavior.

7. Changes in BOPAlgo_WireSplitter, BOPTools_AlgoTools, BRepLib_CheckCurveOnSurface and ShapeAnalysis_Wire to use adaptors instead of geometric entities

8. Allow Geom2dAdaptor and GeomAdaptor in case of offset curve to use corresponding adaptor for basis curve

Modification of test-cases according to the new behavior.

5. Intersection lines are created with their individual step along U1 parameter.
6. Points processing has been moved to the assembly level.
7. Extend output of "bfuseblend" and "bcutblend" DRAW-command.
8. New option for "bfuseblend" and "bcutblend" command has been added.

96a95605cd 0024510: Remove unused local variables
When warnings are enabled, compilers report lots of occurrences

b659a6dc19 0023830: BRepExtrema_DistShapeShape does not find intersection of face with edge
Data member myIsDivergent was added to class math_FunctionSetRoot.
The member is initialized in method Perform start by Standard_False. The member is changed in the method to Standard_True if an approximation point is located outside of search set.

Method IsDivergent was added to class math_FunctionSetRoot.
The method returns value of myIsDivergent.

Parameter theStopOnDivergent with default value Standard_False was added to
a constructor and method Perform of class math_FunctionSetRoot.
The parameter shows whether return from method Perform if myIsDivergent
became Standard_True.

Class Extrema_GenExtCS was optimized for dynamic memory consumption:
the class surface values are not stored now.

Method Perform of class Extrema_GenExtCS was improved for local extreme
search in case of iteration algorithm divergence. Size of the algorithm
grid cell for initial approximation is reduced by 2 in the case. The count
of the reduces is limited.
Build fix in *.cdl.
Case of extrusion was carried out of the repeat loop.

Division method of the 3-dimensional grid (curve param, surface first
param, surface second param) by two was replaced by method of moving the
grid.

The moving method is about two times faster than division method.
Now grid moving method is depending on some average linear sizes of the curve and the surface.
In case (theStopOnDivergent && myIsDivergent) method math_FunctionSetRoot::Perform sets Done to Standard_False and discard it's last solution.
Test case for the bug fix.
Test case correction
Initial approximation was corrected for search of maximum in Extrema_GenExtCS::Perform.
